V MACHINE FOR TREATING HIDES AND THE LIKE.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed. April 30, 1918. Serial No. 231,572.

ing is a specification.

This inventlon relates to apparatus for applying plastic substances to articles.

ore particularly it relates to apparatus for applying hair removing compounds to hides and skins.

In the leather industry the hair is usually removed from the hides and skins by applying to the hide a so-called sulfid compound, usually composed of sulfid of soda and lime. This compound is allowed to remain on the hide fora short time, and has the effect of loosening the hair so that it may be readily removed by a subsequent operation.

The sulfid compound which is used is of a thick plastic nature, and has heretofore been applied by hand because no successful Way has ever been found for applying it mechanically.

One object of this invention is to provide apparatus for mechanically applying hair removing compound to hides and skins.

Another object is to provide an improved apparatus for applying any material of a plastic nature to various articles such as hides and skins.

Other objects of the invention will hereinafter appear.

One embodiment of the invention is illustrated in the accompanying drawings. The views of the drawings areas follows:

Figure 1 is a vertical longitudinal section through a machine constructed in accordance with the invention.

Fig. 2 is a plan view of the machine shown in Fig. 1, and

Fig. 3 is a vertical transverse section taken on the line 3*?) of Fig. 2. H i

One embodiment of the invention will be specifically. described to illustrate the invention, but the specific description should notbe construed in a limiting sense as the in vention may take various different forms.

The machinecomprises in general an end-- less belt upon which the hides or skins are placed. The belt moves the hides under the mechanism for applying the sulfid compound thereto. This mechanism comprises a feed hopper containing the compound and a feed roll to which the compound is supplied from the hopper. Located adjacent to the feed roll is the distributing means which comprises a shaft having a series of radially projecting flexible strips or wiping elements. As this shaft is rotated the flexible strips contact with the surface of the feed roll, remove the adhering sulfid compound therefrom and throw it onto the surface of the hide. The feed roll is rotated at a relatively'slow speed, but the distributing roll rotates fast enough so that the flexible strips will strike against the feed roll in rapid successionand throw the material onto the surface of the hidein such a manner that the entire surface of the hide will receive a uniform coating of the compound.

The machine comprises various other intrumentalities such as scraper mechanism for removing the urplus sulfid compound from the endless belt. A trough receives the compound scraped from the belt and this compound is then pumped back to the supply hopper.

The embodiment of the invention illustrated in the accompanying drawings comprises a suitable framework 1. A roller 2 is journaled at the forward end of the framework 1 in bearing boxes 3 which may be adjusted longitudinally of the framework by means of the adjusting screws 4.

A second roller 5 is journaled at the rear end of the framework 1 and an endless belt 6 passes over the two rollers 2 and 5. By turning the adjusting screws 4: the tension on the belt 6 may be regulated.

The belt 6 is operated by means of a driving shaft 7 which extends transversely across the machine near the rear roller 5. At one side of the machine the driving shaft 7 carries a loose pulley 8 and a fixed pulley 9. These pulleys may be rotated from any suitable source of power by means of the belt 10. The other end of the driving shaft 7 carries a pinion 11 which meshes with a gear 12 secured to the end of the shaft upon which the rear roller 5 is mounted. This driving mechanism will impart rotation to the rear roller 5 and also to the endless belt 6 and the other roller 2.

A supply; hopper 13 is mounted over the belt 6. This hopper is adapted to contain the sulfid compound to be applied to the hides. A feed roller 14 rotates adjacent t'd the supply hopper 13 and receives upon. its surface a coating of the sulfid compound from the supply hopper. The feed roller 14c is rotated at a relatively slow peed from" the shaft of the roller 2. As shownlin Fig;

2 this shaft carries a sprocket 15 from which rotation is imparted by meansofthe chain 16 to a sprocket 17* carriedby'the-shaftbf the feed roller 14.

Journaledin the framework adjacent'to the feed roller 14 is the'distributing-@means Which comprises a shaft 18and a plurality;

of radially projecting flexiblestrips or wiping elements 19. In the present instance there are four of thesefiexiblestrips, but

there mav be'as many as desired. Each of. across the; machine throughout the entire length of the feed]- These strips may be associatedwith-the shaft 18 in any suitableway, but

the strips extends roller 14 in the present instance they'are'f-secured at speed'at which-the feed roller 1 1 is rotated. The parts are so positionedthat when the shaft 18 is rotated in the direction indicated by the arrow, the flexible strips 19 will strike} against the surface of theffeedrollerl l, re-

move the adhering sulfid compound there-f from, and throwit down toward'thebelt 6:

The feed roller 14 and the distributing means mayibe inclosed by a guard-orcasing 22l 7 The hides or skins to be treated are placed upon the belt 6 atthe forward end of the machine. As they pass under the distributing means the lattersupplies to thesurface; of the hide a uniform coating of the sulfid compound. The rapidly revolving flexible H strips 19 strike the surface-ofthefeed roller 14 inrapid SIl'CCGSSlOI 1, I6HlOV6 the sulfidcon pound therefrom, and throw it down on to is thrown on to thesurface of the hide a substantially continuous manner, so that :the hide receives a uniform coatingofthe sulfi'd compound. \Vhen the hides reach the rear end of the machine they are removed by.

hand or any other appropriate means.

The sulfid compound whichfalls upon the belt is removed by meansof the scraper 23- which passes transversely across'the machine under the roller 5. The scraper- 23 is 'carried by a series of brackets'24 secured to a shaft 25 which is loosely mounted in the framework. A bracket 26 (Fig. 3) is secured to the shaft 25 intermediate its ends, and is providedwith a projecting arm 27 (Fig. 1) adapted to support a weight 28. The, weight 28 serves to bias' the shaft 25 in su'ch -a" w'ay" a's*t'o* force the scraper 23 againstthesurface of the lower run of the V endless belt; The force with which the scraper 23 is pressed against the belt may be regulated by shifting the weight 28"along the armQZ.

The material removed from the belt by the scraper 25 falls into a trough-29 extending; transversely! aoross: the machine just below the scrape-r. A-guard" 30 carried by the trough 29 7 projects toward the reals' of "the Ilia-China a" sufiioientdistanee to; catch any inaterialavliiehnnay fall from the beltjbefore it reachesthesscraper. This guardis; in

clined as shown in Fig. 1 soflha-t-anymaterial dropping-thereon will flow into' the trough29.

A conveyer 31rotates in :tlietrouglil29. It

may-be operated-in anysuitable way. In

the present instance it is driven from sprocket carried by the driving shaft 7 (Fig. 2) by means offa chain 3,3 passingwover a sprocket 34; carried bythe conveyer; shaft."

The conveyerserves to-move the sulfidcompound toward the end of-the trough to articles vari usmareri'ais of a thickplas tic nature. Thepres'eiit'macliine constitutes efiicient means for doing vthis mechanically and rapidly.
